The bug is real, and it's not any of those proposed. The Real Problem is that
the floating point format that is actually installed is NOT the 53-bit format
that FreeBSD wants to use.
I guess Zack's conversion to cpu-modes.def files was not 100% correct. In any
case, the SUBTARGET_OVERRIDE_OPTIONS definition in freebsd.h is not effective.
It probably happens too early.
Seems like a cleaner solution here would be a TARGET_53_IN_96_LONG_DOUBLE macro
to be used in the existing ADJUST_FLOAT_FORMAT directive that we already have.
